Best practices before connecting MetaMask to third-party dApps?

Support

Hi MetaMask Community,

I’m trying to understand safer wallet practices before connecting MetaMask to any third-party dApp or online platform.

I am not here to promote any website. I only want to learn the correct safety process from experienced MetaMask users.

Before connecting MetaMask to a platform, what should a user check?

For example:

  • Is it better to use a separate wallet for dApps instead of a main wallet?
  • Should users keep only a small amount in the connected wallet?
  • How can users review token permissions after connecting?
  • What is the safest way to revoke old approvals?
  • How can users confirm they are on the correct network?
  • What warning signs should users look for before approving any transaction?
  • Are there official MetaMask guides or community threads you recommend for this?

I already understand that users should never share their secret recovery phrase, private keys, or passwords with any website or person.

I’m mainly looking for general safety advice around wallet connection, permissions, approvals, and dApp usage.

Thanks in advance for any helpful guidance.

That’s a great question on web3 safety practices. A few good wallet safety habits include but not limited to the following
‎
‎I would use a separate (hot) wallet for interacting with dApps, and keep my main holdings in a separate wallet (ideally a hardware wallet for larger amounts).
‎
‎I would only keep the funds I need for transactions in the wallet I connect to dApps.
‎
‎Always double check you’re on the official website (watch for phishing URLs) before connecting your wallet.
‎
‎You can easily verify you’re on the expected network on MetaMask before signing or sending transactions.
‎
‎Make it a habit to always read every MetaMask prompt carefully and check what you’re approving, the spender/contract, the amount (especially “unlimited” approvals), and whether you’re signing a transaction or just a message.
‎
‎Regularly review and revoke token approvals you no longer need using trusted approval management tools like Revoke.cash or the token approval features available in supported wallets.
‎
‎Aways disconnect your wallet from dApps you no longer use, and keep MetaMask and your browser up to date.
‎
‎You can find more safety guidelines on the official MetaMask support website on wallet security best practices and avoiding common scams.

Thanks for the detailed advice. This is helpful.

I also use MetaMask with Rillex, so I’m trying to follow safer wallet habits instead of connecting my main wallet everywhere.

I’ll use a separate hot wallet for dApps, keep only a small amount for transactions, double-check the official website URL, confirm the network before signing, and review approvals regularly.

I also understand that I should never share my Secret Recovery Phrase, private key, or password with any website or person.

Appreciate the guidance.
